If the camera was on free run and not rec run here is what I do.
Make a seq and lay in the first clip in. Match the seq’s TC to the Clip’s, then lay in the 2nd clip so the TC lines up. This will create a gap where the camera was stopped. Export this will current settings (not self-contained) and use this in your multicam clip.
This really helps if all the cameras were TC locked but it give a solid video clip with an easy way to check for other breaks and bypasses the need to do any math, which is always a good thing.
